Fallout: Australis concept work

My art style has never really qualified as "fast" and/or "loose", but that's what I was trying to channel here.  Maybe 3 or 4 hours total, working as fast I was able.  Plenty that's awful or ineffective, but there are bits of this I quite like.
Fallout: Australis is still a thing in the back of my head...bolstered by Mad Max, it keeps reappearing.  Mad Max, but with ghouls and an invading Imperial Robot Army.   And plasma rifles.

Experiments

I know very little about skintones/color theory, etc. Experimenting to try and figure some things out.

Also a leisurely reprieve whilst trying to recover from a pinched nerve (resulting in shooting pain the length of my dominant arm.
